Hi M.,
My daughter had lice last week. I don't know anything about Licex although I saw the same tempting online advertisement. But from the Pediatric nurse and the School nurse I talked to and other websites about lice, there's no "easy" solution.
You HAVE to remove the nits by hand. Even the combing doesn't work 100%. The combs will remove the lice but not the nits which stick to the hair shaft with a type of glue. My daughter has beautiful,long, thick hair and after the lice killing shampoo treatment (Walgreen's) it took us 10 hours over the course of 2 days to remove all the nits (eggs) which are mostly on the hair closest to the scalp where it's warm for the nits.
I sat at my computer desk and she sat in kitchen chair which was shorter than my chair, I sectioned her hair with bobby pins and with a desk lamp began to pull out the white eggs one by one, hair shaft by hair shaft. Yes, 10 hours.......my shoulders, neck and head were on fire and you can imagine trying to get a child to be still to do this....it's awful. She had to stay home from school, and I took a day off work to accomplish this task --(and it's recommended to treat the entire household if they have symptoms, I treated my boys and myself even without symptoms)
During the time I was removing the nits,I laundered everyone's bedding, jackets (anything in contact with her long hair) in hot water, bagged up stuffed animals and her back pack (for 2 weeks) and have been checking her hair for nits I missed every single day since. The shampoo kills the lice but not necessarily the nits which can hatch within 1-7 days. A female lice can lay up to 200 eggs. If that happens you are back at the beginning.
M., please remember this -- it's no one's fault. Lice prefer clean healthy hair and scalp, it's not about "dirtiness" or anything of the kind. Lice happens. My daughter felt ashamed and kept apologizing.......it's certainly a stigmatism that needs to be understood more.
I hope I've helped you a little bit.
Cherie'
